Rollfast seatpost

[Phrank Vee]

Hey All,
I’m new to building vintage bikes. I’m currently having trouble finding a seat post for my 60s Rollfast tank bike. I think it’s a 21.1 Any suggestions on locating one. Didn’t think this part would be that challenging.

That is about 13/16 and in those days seat posts came in inches. 13/16 is a very common size. You might have to tighten the clamp a bit more or use a thin shim. Roger
